Revision summary
Forensic anthropology estimates sex, age, stature and trauma from bones and teeth, and it records context. Krogman and Stewart standardised osteological identification. DNA STRs and dentistry confirm identity when references exist. Clyde Snow’s human-rights cases show remains as testimony. Facial reconstruction uses tissue-depth markers, as in Gerasimov and Gatliff, now often with CT and 3D prints. The face is an approximation to prompt recognition, not a certain portrait. Ethics include family consent and no racial or caste over-claim.
Model answer
Introduction
Forensic anthropology reads human remains to help the law answer who a person was and what happened to the body. Bones, teeth and, where available, DNA are the evidence. Facial reconstruction is one specialised technique for suggesting a face when identity is unknown. It is an aid to recognition, not a photograph from the grave.
Body
Utility of human remains
Wilton Krogman and T. Dale Stewart built the modern osteological toolkit. In the field or mortuary, the anthropologist first asks whether the remains are human, how many individuals are present, and how long they have been dead.
- Biological profile: Pelvis and skull inform sex estimation. Teeth and bone fusion inform age at death. Long-bone length informs stature. These are estimates with error, stronger for adults than for children, and never a caste certificate.
- Ancestry estimation is the most abused limb. Metric and morphoscopic methods speak in probabilities about continental affinities. They must not be sold as a racial ID.
- Trauma and taphonomy: Blade, bullet, blunt force, burning and animal chewing can be distinguished if the bone is read with C. K. Brain’s caution from palaeoanthropology: not every mark is a weapon.
- Context: Mass disasters, unmarked graves, and unidentified dead on Indian railway lines or after floods need osteology plus scene recording. DNA STRs confirm identity when a family reference exists. Odontology and surgical implants help.
Clyde Snow’s work with the disappeared in Argentina showed the political utility: remains can testify when the state denied the death. Disaster-victim identification after tsunamis and air crashes is the humanitarian twin.
Facial reconstruction
The technique builds a face on a skull using average tissue-depth markers at standard points, then models muscle and skin. Mikhail Gerasimov developed a well-known anatomical method in Russia. Betty Pat Gatliff and colleagues developed an American clay method. Today CT scans and 3D printing often replace purely manual clay.
It can produce a recognisable approximation that jogs a relative’s memory or a public appeal. It cannot recover exact eyes, hair, expression or age-related fat. Two reconstructors will not make identical faces. When DNA or dental records exist, they outrank a clay likeness.
Police 3D reconstructions of unidentified skulls, sometimes released in newspapers, are investigative leads, not courtroom certainty.
Ethics
Consent of families, dignity of the dead, and caution with caste or community labelling are part of the method. Display of remains for teaching is a separate ethical file from forensic casework.

Conclusion
Human remains give a biological profile, a trauma history and, with DNA, a possible name. Facial reconstruction is a tissue-depth approximation used to prompt recognition. Krogman, Stewart, Gerasimov and Gatliff developed the toolkit. Error, taphonomy and ethics belong in the same account as the technique.

-
Can a reconstructed face be used as unique identification?
No. It is a public or investigative lead. Positive identification needs DNA, dental records or a unique medical device, plus context.
-
How is this different from palaeoart of hominins?
The forensic case has a real individual and a legal purpose. Hominin faces are scientific illustration with even wider uncertainty.

Mendelian and non-Mendelian traits.
Mendelian genetics in man-family study, single factor, multifactor, lethal, sub-lethal and polygenic inheritance in man.
Mendelian traits follow one-locus segregation and can be read in a pedigree. ABO, PTC tasting, albinism, haemophilia A and Huntington disease are standard examples. Multiple alleles and sex-linkage extend Mendelism; they do not cancel it. Non-Mendelian traits include polygenic stature and skin colour, linkage, maternal mtDNA and imprinting. Environment plus many genes gives a curve, not a 3:1 ratio. Use family study for Mendelian markers and quantitative genetics for everyday variation. Single-factor, multifactor, lethal and polygenic inheritance is this same distinction.

Theoretical significance of Purum kinship-system.
Kinship
The Purum are a Kuki-Chin group used by Needham as a test case for alliance theory. The claim was prescriptive marriage to mother’s brother’s daughter, with wife-givers and wife-takers in a cycle. Needham argued against Homans and Schneider: the pattern is structure, not sentiment. The case mattered because it took elementary structures beyond Australia and clarified prescription versus preference. Ackerman and others showed that the tables did not seal the cycle as neatly as the model. The lasting names are Lévi-Strauss, Needham and the model–practice gap.

Osteodontokeratik culture and its makers.
Paleolithic
Osteodontokeratic means a supposed bone–tooth–horn culture named by Raymond Dart at Makapansgat. The claimed makers were Australopithecus prometheus, now placed in Australopithecus africanus. Dart read clubs, saws and daggers from antelope parts, and inferred hunting and violence. C. K. Brain showed that leopards, hyenas and cave processes explain much of the assemblage. The idea survives as a taphonomy lesson, not as a real industry. Osteodontokeratic is defined by site, claimed maker, and the later critique.
